The rockchip spdif driver uses SIMPLE_DEV_PM_OPS to conditionally
set its power management functions, but we get a warning
about rk_spdif_runtime_resume being unused when CONFIG_PM is not
set:
sound/soc/rockchip/rockchip_spdif.c:67:12: error: 'rk_spdif_runtime_resume' defined but not used [-Werror=unused-function]
This adds a __maybe_unused annotation so the compiler knows
it can silently drop it instead of warning.

Explicitly set the transmit data level on the transceiver to 16 samples
rather then the default 0. This matches both the level set in the vendor
kernel and the (seemingly very similar) i2s engine. This fixes audio
glitches when playing back at 192k rate.
At the same time, fix a trivial typo in the TDL mask definition

there maybe more than one i2s module inside chip, and these i2s modules
have different channels features.
for example: there are 3 i2s in rk3066, one support 8 channels playback
and 2 channels capture, but the others only support 2 channels playback
and 2 channels capture.
in order to compatible with these various chips, we add playback and

The rk_spdif_probe uses the device match data as a token to identify a
particular device, but accidentally casts a pointer to 'int', which is
not portable, as gcc points out in this warning on arm64:
rockchip_spdif.c: In function 'rk_spdif_probe':
rockchip_spdif.c:283:6: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
This changes the logic to compare two pointer values instead, using
the same cast that was used for initializing the value in the first
place.

It is equal to the watermark level.
That is, the dma_tx_req signal is generated when the number

Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform

removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There are
some ath9k patches coming in through this tree that have been acked by
the wireless maintainers as they relied on the debugfs changes.

Currently, CONFIG_SND_SOC_ROCKCHIP_I2S could also be selected
without having CONFIG_SND_SOC_ROCKCHIP enabled.
As this makes no sense, a Kconfig dependency is added to
CONFIG_SND_SOC_ROCKCHIP_I2S. This will make the item visible only if
CONFIG_SND_SOC_ROCKCHIP is enabled.
Additionally, as the code connected to CONFIG_SND_SOC_ROCKCHIP_I2S
depends on CONFIG_SND_SOC_GENERIC_DMAENGINE_PCM, the dependency
is moved to reflect this more clearly.
